ArcPy 批量给shp字段赋值

工作中需要做大量图层的拼接，为了在拼接完成后还能知道原始数据文件是什么，所以写了个Python脚本对每个图层的SOURCE字段进行赋值。

附上Python代码：

 # -*- coding: utf-8 -*-
 # nightroad
 import sys
 import arcpy

 path = "C:/Users/nightroad/Desktop/SHP"
 arcpy.env.workspace = path
 ff = arcpy.ListFeatureClasses()
 for fc in ff:
     print(fc.replace(".shp", ""))
     arcpy.CalculateField_management(fc,"SOURCE",'"'+fc.replace(".shp", "")+'"',"PYTHON_9.3")
     print('Success:'+fc)
